B. C. F. Townsend Cromwell May 1964 Cruise The May 1964 Townsend Cromwell cruise was the fourth of a series of cruises run by the U. S. Fish and Wildlife Bureau of Commercial Fisheries covering a fixed grid to the east of the main Hawaiian Islands for the purpose of determining the variations in structure of the water masses and currents of this area. The cruise started 17 May 64 and ended 5 June 64, covering approximately 1,600 miles in 20 days. Pacific Project personnel maintained daily sunrise to sunset bird observations for a total of 253.1 hours. In addition Project personnel aided in recording weather observations and in taking bathythermograph traces. Project personnel included David Bratley and Warren King. Upon availability of oceanographic data, an attempt will be made to correlate bird distribution with prevalent oceanographic conditions of the cruise.
